<p>The device includes a pair of passages (4-4') meeting at a top neck (5) communicating with and coupled laterally to the outlet of the mill (1). The junction between the passages (4-4') has a hinged trapdoor (7) which in a stable position seals one of the passages whilst holding the other one open. The passages (4-4') are closed at the bottom by rotatory trapdoors (14-14') which may be driven by activating two electric magnets that are activated by respective microswitches (18-18') lying beneath the passages (4-4'), and hence the arrangement of the cup (19) to receive a measure of coffee brings about an activation of the electric magnets and thus turning of the respective trapdoor (14-14'), an upright arm (22-22') being at the same time driven which acts upon a balance lever (10) solidly connected to an extension (9) of the mounting pin (8) of the trapdoor (7), causing the latter to swing towards the closed position of the passage (4-4') opposite the passage which supplies the measure of coffee onto the cup (19). <IMAGE> <IMAGE></p> |
